Question

Four runners start at the same point; Lin, Elena, Diego, Andre. For each runner write a multiplication equation that describes their journey.

Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?

7.2*?=29

29*7.2=?

?*29=7.2

Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?

240*26=?

26*?=240

?*240=26

Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?

-6.1 • ? = 33

33*?=-6.1

-6.1*33=?

Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?

-295*38=?

38*?==-295

?*-295=38

Answer 1

See the answers in the explanation

Explanation:

Lin runs for 29 seconds at 7.2 meters per second. What is her finish point?

time= 29 seconds

speed= 7.2 m/s

distance= speed*time

distance= 7.2*29

distance=208.8 m

Elena runs for 26 seconds and finishes at 240 meters. What is her velocity?

time= 26 seconds

distance= 240meters

velocity= distance/time

velocity= 240/26

velocity=9.23 m/s

Diego runs for 33 seconds at -6.1 meters per second. What is his finish point?

time= 33 seconds

velocity

distance=velocity*time

distance=33*6.1

distance= 33*6.1

distance=201.3 m

Andre runs for 38 seconds and finishes at -295 meters. What is his velocity?

time= 38 seconds

distance= 295m

velocity= distance/tim

velocity= 295/38

velocity= 7.76m/s
